<p><p><h2> Summary of Example Specifications</h2><div class="grayed-title subsection"><strong>Specification Name/Number:</strong> Eastside LRT Project 02153-1 Ground Treatment</div><strong>Reference(s):<br></strong><em>Los Angeles County Metropolitan Transportation Authority</em></p><p>This specification gives guidance for grouting as a means of structural support during excavations. This specification limits grouts to the use of liquid sodium silicate or cement-based grouts. The specification covers all relevant components needed to ensure a successful grouting project and could be used as a guide in development of other project specifications for structural grouting projects. It is a well organized specification and is easy to follow. </p><p><div class="grayed-title subsection"><strong>Specification Name/Number:</strong> Guide Specification for Underpinning by Chemical Grouting</div><strong>Reference(s):<br></strong><em>Hayward Baker</em></p><p>This specification gives guidance for grouting as a means of structural support during excavations. This specification limits grouts to the use of liquid sodium silicate based grouts though modifications to the content could be made to allow information to be inserted for various other types of chemical grout. The specification covers all relevant components needed to ensure a successful grouting project and is intended to be used as a guide in development of other project specifications for structural grouting projects. This outline seems to be similar to that used in many highway and non-highway related specifications. This document is only a guide and Hayward Baker recommends tailoring specifications towards site specific conditions and design requirements. </p><p><div class="grayed-title subsection"><strong>Specification Name/Number:</strong> Specifications, Supervision, and Inspection</div><strong>Reference(s):<br></strong><em>Karol (2003)</em></p><p>This textbook is a comprehensive source for information related to chemical grouting both for structural improvement and water control. The information contained in this text is valuable for specification development. Chapter 21 of this text book titled “Specifications, Supervision, and Inspection” includes a variety of excerpts from various specifications, which can be used as models for specification writing. Also included in Chapter 21 are flow charts and recommendations as to what specifications should contain. This chapter also provides suggestions and strategies for supervision, which can be considered application of specifications. </p></p>
